Fire-Lite PAM-1 — encapsulated multi-voltage SPDT relay module with an energized-coil LED.
Manufactured by Air Products & Controls and catalogued by Fire-Lite, the PAM-1 is the general-purpose interposing relay used where a panel output must drive something it cannot switch directly — a door holder, a fan shutdown or a damper. It is fully potted and hangs on its own leads.
- One SPDT dry form C contact: 10 A at 120 VAC, 7 A at 24 VDC, 250 µA at 5 VDC
- Coil takes 24 VAC, 24 VDC or 120 VAC; inputs are polarity-sensitive and diode-protected
- Coil current 20 mA at 24 VDC, 50 mA at 24 VAC and at 120 VAC; pull-in under 1 s
- Red LED lights whenever the coil is energized
- Six 12 in. 18 AWG flying leads, with wire nuts, screw and tape
- 1.50 x 1.20 x 0.77 in.; 32 to 120°F
- UL S3403, MEA 73-92-E Volume 21, CSFM 7300-1004:101
Check the coil before substituting a sibling: the PAM-2 switches 7 A on a 12 or 24 VDC coil, the PAM-4 spans 12 to 40 VDC and carries no LED, and the PAM-SD runs on 20 to 32 VDC, switches 7 A and adds a seventh lead so a supervised circuit can pass through it.

FAQ
What voltages can energize the PAM-1?
One of three coil voltages: 24 VDC, 24 VAC or 120 VAC. The inputs are polarity-sensitive and diode-protected.
What can it switch?
One SPDT dry Form C contact rated 10 A, for remote control or status feedback in HVAC, fire alarm, security, lighting and building automation systems.
Does it have a status LED?
Yes. A red LED lights when the relay coil is energized.
How is it mounted?
It is packaged with a self-tapping screw, double-sided tape and wire nuts, so it can be fixed almost anywhere.
